Not since “Pretty Woman” have so many young beauties turned out for a polo match. And it wasn’t just any polo match — it was the U.S. Open Polo Championship semi-finals at the Greenwich Polo Club in Greenwich, Conn. It was between the Revlon and White Birch teams, and it marked the tournament’s first visit to the Northeast in 40 years.

“My boyfriend is on the White Birch team,” said Stephanie Seymour, referring to Peter Brant. Seymour added that the relationship has gotten her into the sport.

“I’m a big polo fan,” she said at a pre-match luncheon and Ungaro fashion show hosted by Cartier.

For fellow model Beverly Johnson, it was a polo premiere. “I’ve done polo photo shoots before, but I’ve never been to a match,” she said.

Billy Baldwin and Chynna Phillips came out to watch their friend Neil Hirsch, also on the White Birch team, swing his mallet. “I once went to a polo match in London,” recalled Baldwin. “I was on a press junket for a movie, and I thought it would be an interesting morsel of culture to experience. Prince Charles was the last one to hit the ball, and when it was over, I’m embarrassed to say, I went onto the field and took the ball and kept it.”

Henryk DeKwiatkowski’s undefeated Calumet team didn’t play this day, but even if it had, he would have been seated in the crowd rather than in the saddle.

“I broke my hand in the first game,” he said. “But my son has been playing instead. It makes me really proud to watch him.”
